Nick Diaz is a polarizing character in the MMA world, he is brash, disrespectful and he is very talented. Tonight he successfully defended his Strikeforce Welterweight Championship against Chute Boxe's Evangelista "Cyborg" Santos. Mr. Cyborg was coming into this fight off of a two-fight win streak, with a win over Marius Zaromskis in Strikeforce and Paul Daley's uncertain future setting this fight up for him. Mrs. Cyborg was in the audience to support her husband and the storyline going into this fight was Cyborg had really turned his career around and improved vastly.

The first round was an incredible brawl, with Cyborg's technique dominating early in the round. Cyborg worked a brilliant game plan early on, working the leg kicks and following up with some crisp punches. With Diaz reeling most of the early parts of the round, a right hand from Diaz and a flurry was able to change the atmosphere of the fight. It turned into an all-out brawl afterwards and Cyborg looked as if he was slowing down.

The second round saw neither man looking to give an inch. Cyborg's game plan began to fall apart as he simply started looking to take Diaz's head off. As soon as he stopped working the leg kick the fight began to slip from his grasp. Diaz was starting to take advantage of this and was hurting Cyborg standing up, forcing Cyborg to take Diaz down. This proved to be a mistake, though, as Diaz slipped on an armbar to secure the win.

The night also saw Robbie Lawler put up a good fight against Ronaldo "Jacare" Souza until it went to the ground, with Jacare choking Lawler out, disproving the "Beard Theory." Herschel Walker remains undefeated against hand-picked opponents in Strikeforce, which they'll note over and over again. Roger Gracie showed a well-rounded game, but finished with his grappling against Trevor Prangley.

If you were to stop and try to think of who two of the biggest UFC stars would be, I'd like to think that at some point your brain would scan to -- or at least consider -- Anderson Silva and Nick Diaz. That is why a fight between the two of them would be such a big deal. Anderson Silva is still primed for a big return after having his shin shattered at UFC 168 against Chris Weidman and his manager tossed out the name Nick Diaz as a possible opponent.

But would Diaz take the bait? Kind of. According to Ariel Helwani from UFC Tonight last night, Nick Diaz would love to fight Anderson Silva, but he'd want the UFC to pay him accordingly for such a huge fight. Nick Diaz has been "retired" of late, in part due to how things went down against Georges St-Pierre, but also because he wants more money from the UFC and Dana White doesn't seem willing to whip out that fat Zuffa checkbook for him just yet.

For a fight like this, though? I feel like the UFC would be silly not to pay both of these guys a lot of money and hype this as one of the biggest super fights in company history.

Anderson Silva has been out with that horrific injury to his leg since December now and there have been conflicting reports about his possible return. Could it be in 2014? Maybe pushed back to 2015? It looks like 2015 will be the time when we see Anderson Silva return, Ed Soares explained to MMAFighting, listing off possible opponents for Anderson's return. The name that stuck out? Nick Diaz.

"There's Michael Bisping, there's Cung Le. Even Nick Diaz," Soares said. "Nick Diaz has said he's wanted to fight him before. Nick Diaz wanted to box Roy Jones Jr. You could argue that Nick Diaz and Anderson probably have some of the best boxing in MMA, so we'll see what happens. Like we all know, so many things can change, the landscape of the sport can change so much in such a short amount of time.

"There's not a shortage of talent that the UFC has, so I'm sure the UFC is going to come up with a good plan on who the next opponent should be, and I'm sure it will be a good fight."
